beqom interview questions

I had a first interview and never heard back from them company, even though they promised updates in a week. It's fine if they find someone more qualified, but if someone respects you with their time, and prepares for the interview, being transparent is the bare minimum. The interviewer was a but late plus he didn't ask any questions, he was visibly bored. Why do you bother to interview, if you are not interested in the candidate?
